Hi all,
I'm trying to manually find the peaks of a graphed data set using my cursor. However, this method doesn't seem the most precise. Is there a way to lock it on my graph? Or is there a way to transform where I clicked on the graph to the closest data point?
For reference, I'm currently using ginput to identify potential datapoints. I attatched blow what the cursor currently looks like

How about using the findpeaks function instead?

I did that on another program, but not all of the peaks are found (and some other datapoints that are not peaks were labeled as peaks). I'm trying to make it more selective after conducting the findpeaks function.
